Phase differences between primary-side (200) series-connected first (S1) and second arms (S3) and secondary-side series-connected fifth (S5) and sixth (S7) arms and between primary-side series-connected third (S3) and fourth (S4) arms and secondary-side series-connected seventh (S7) and eighth (S8) arms are controlled for power being transmitted from the secondary side (300) to the primary side (200). Turn-off of the fifth arm is corrected to cause an integrating result of a secondary coil (304) current for an interval delayed by a current sensor response delay from an interval between turn-off of the first arm and turn-on of the seventh arm to approach zero, or turn-off of the seventh arm is corrected to cause an integrating result of the secondary coil current for an interval delayed by the response delay from an interval between turn-off of the third arm and turn-on of the fifth arm to approach zero.
